The previous trimaran Banque Populaire X is still, since 2009, the record holder of the North Atlantic crossing in 3 days 15 h 25 men 48 s, so an average speed of 32,94 knots, inc. a record 907 NM in 24 h :

I saw those drawings the other day but I couldn't figure out if I was seeing a foil on the daggerboard or a rudder T-foil or both. I finally decided it must be a rudder t-foil.
The ama uptip foils are obvious. I like Len Surtees-I'll see if I still have his e-mail. I'm having good luck with responses these days-I'm on a roll I guess......
UPDATE-I didn't have it but finally ran across it and sent him an e-mail. Maybe he'll write back!
